Frequently Asked Questions
1. What silicone products do you manufacture?
We produce liquid silicone rubber, silicone rubber, silicone oil, and platinum agents. Our silicone products come in different viscosities, hardness levels, and densities to meet specific client requirements.
2. Do you offer free samples to clients?
Yes, we can provide samples for testing purposes.
3. How is quality controlled in your factory?
We have a professional QC team and each batch undergoes thorough testing through our quality examination system.
4. How to remove bubbles during mold making?
After mixing liquid silicone with curing agent, place the material into a vacuum machine to remove bubbles.
5. How to extend silicone mold lifespan?
Choose the right liquid silicone for your product, avoid using silicone oil in mold making, and allow the mold to fully cure for at least 2 hours after completion.
6. Why does silicone rubber produce bubbles when mixing with curing agent?
This is a normal physical phenomenon. The liquid produces bubbles during mixing, which must be removed through vacuum treatment.
